摘要：
The paper reports the results of our study on the dynamics of model phospholipid membranes studied by P-31 NMR spectroscopy. The P-31 NMR spectra of multilamellar vesicles in temperatures below the main phase transition of PC are reported. The P-31 NMR spectra revealed changes caused by an increase of the membrane fluidity when polysialic acid (polySia) was applied as a modifying agent. The presence of polySia in the external environment of the phospholipid vesicles changes the motional freedom in the region of phosphate group of lipids. Increase of polysialic acid concentration changes structural properties of a membrane by increasing its fluidity. (C) 2003 Elsevier Inc. All rights reserved.
